Other fuel system problem on the 2009 Toyota Corolla
1 crash 1 of the 19 reports for this failure mention a crash, a fire, an injury or a death. Those are the owner's words on the complaint form, not a verified finding, and one report can mention more than one.
When other fuel system problem gets reported
Owners of the 2009 Toyota Corolla report other fuel system problem at a median of 30,000 miles. A quarter of the reports come in before 15,000 miles and a quarter after 40,000 miles, from 17 reports that carried an odometer reading.
A part like this is normally expected to survive 90,000 miles. It is the 15th most-reported problem on this model year.
The mileage distribution
The reported range runs from 5,000 miles at the tenth percentile to 70,000 miles at the ninetieth, a spread of 64,534 miles across the middle 80% of reports.
When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.
65% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 7,400 miles | 16,273 miles | 28,900 miles | 40,000 miles | 71,934 miles |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Of these reports, 1 a crash is mentioned. Owners write their own complaints and the agency does not verify them, so read this as what the reports say happened rather than as a confirmed count.
Putting it right typically runs $300–$2,200 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
The same failure on other years
The same failure is reported on 21 model years of this car. It shows up earliest on the 2016, at a median of 5,000 miles, and latest on the 2014 at 145,000 miles.
By volume the 2019 carries the most reports, with 27; the 2009 has 19. A mode that appears across most years of a model is usually a design choice rather than a bad batch.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

I have a 2009 toyota corolla. It accelerated while I was waiting for the traffic light to turn red to green. The RPM shot up so I put in neutral and then the RPM rapidly shot up to the red mark so the turn off the engine and parked it at my work since evening of 11/05/09. *tr
2009 toyota corolla, "s" automatic transmission. The problem was initially identified by me when my car would not catch while on a slope in drive. The transmission would roll back. The dealership said this was normal due to a loss of pressure, however it would do it even if I barley stopped on a gradual incline for a few seconds. This has caused me to roll back unless I had one foot on the brake and one foot on the gas while to keep me steady to start. This happened at from the time I purchased the car. Recently, I my engine has been running really rough and winding at a high pitch while driving. It now intermittently goes between gears and downshifts automatically into gears that are not appropriate for the speeds traveling. This causes a drastic down speed, and example is I will be on the freeway traveling speeds between 50-65 and it will downshift and reduce my speed to 40 MPH or less, then I will try to accelerate and it will redline out, as if I am in neutral and I will have no control to regain speed until it automatically pushes itself back into gear, and then increases my speed at a rapid pace, without me putting my foot…

How far this goes
Complaints are voluntary, so 19 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.

What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
